Hi Dell Community,
Please help me to diagnose what is wrong with my new laptop.
My Laptop is Dell Latitude E6440 but every time i connect external monitor to my laptop HDMI port via HDMI to VGA converter, the external monitor always blink randomly every couple of seconds. This HDMI to VGA converter is working fine when i used it to other laptop.
Currently i still don't have chance to try my laptop HDMI port to connect directly to HDMI monitor because i don't have it.
Are there anybody have the same problem with me? thanks for your help.
Solved! Go to Solution.
Hi M. Zemmy Indrapatih,
Thanks for your post.
Sorry you are having difficulties with your laptop and monitor. If you could send me the name and model cable adapter you are using and the name and model of the monitor, I might be better able to understand the issue. Thanks
What's the other laptop model? What VGA monitor are you connecting to?
You are best getting a new monitor with HDMI connector.
As you noticed, a HDMI to VGA converter has to convert the digital signal to analog. It may not work with all equipment.
I thought I might jump in here, as I am having the same issues as Zemmy. At work I was issued an e6440, and had the same problem. The IT department swapped it out with another of the same model, new cables etc... and the problem has not gone away.
Updated windows etc...
It would seem that it is a hardware issue.
Any Insight on how to fix?
I'm running into the same problem here. VGA seems to work fine but when I use an HDMI for an extended desktop, the Monitor will start flickering on and off. This seems to only happen when the laptop is connected to a charger.
We are running Latitude e6440s and it is a problem for more than 1 device.
A solution to this would be greatly appreciated.
I'm also having a E6440 where the display starts flickering are being in use for some minutes. It only happen if I connect via HDMI and it happens on two different displays.
Have you tried adapting hdmi to dvi. I haven't tried this yet but don't want to spend the $$$'s if it doesnt solve the problem.
Thanks for the hint to use HDMI (laptop) to DVI (display) adapter. It works neither. Yesterday Dell changed my motherboard. Still the same issue.
I've noted something that seems to work pretty well.
I've been able to use this as an interim solution, (unplugging the power from the back of the machine, and plugging it back in back in a few times during the day)... until Dell figures it out.
Hmm... i will try this solution.. But if this works, too bad its still not fix the problem.
Do you think this is hardware issue or software issue?
Does anyone have tried to test it on different OS? Like windows 7/Windows 8 or Windows 10?
